WINDOW-SCREEN.

To all whom it may concern Be it known that I, GIUSEPPE CAvAoLmuI, a. citizen of the United States, residing at Los- Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Window- Screens, of which the following is a specification.

This invention relates to a window construction and particularly pertains to a screen therefon It is the principal object of this invention to provide a window screen which may be BfiSlly positioned over a window opening and may be instantly removed from its obtructing position.

Another object of this invention is to provide a window sc'reen which may be incorporated within the window frame structure and tnay be allowed to roll up within the frame, or e draw therefrom to any desired lelftilx v nether. object of this invention is to provide simp e means whereby access to the screen mounting may be obtained without" dismantlingthe window frame and which will permit the screen fabric to be readily when desired. a

It is a further ob ect of this invention to provide a window screen of the above class requiring inexpensive and simple mount ticularly disclose the ings and'which will not interfere with the swinging movement of the easement windows-upon which it is used.

Other objects will appear hereinafter.

The invention is illustrated, by way of example, in the accompanying drawings in which:

Figure 1 is a view in elevation illustrating a window frame with parts removed to parmounting of a window screen therein, said screen being constructed according to the spirit ofthe present invention.

Fig. 2 isan enlarged fragmentary view 1n v elevation illustrating the wlndow screen and disclosing in detail its mounting and counter-weights arrangement.

Fig. 3 is a view in vertical section and elevation as seen through the window frame .with parts broken away for the sake of convenience, and clearly disclosing the relation of the screen thereto and the manner in which it may be detachably secured to its roller.

Application filed June 4, 1917. Serial No. 172,665.

Fig. 4 is a view in transverse section as seen on the line 4% of Fig. 3 illustrating the relation of the screen to the window frame and its counter-weights.

is a View invertical section illustrating the window sill and particularly showing the lower portion of the screen as resting upon the sill when an inwardly swing window sash is use Fig. 6 is a view in vertical section similar to Fig. 5 illustrating the disposition of the screlen when an outwardly swinging sash is user. a

Fig. 7 is an enlarged view in section illustrating the lower marginal edge of the screen, and particularly disclosing the mannor in which it is bound.

Referring more particularly to the drawings, 10 indicates a casement window sash which is adapted to swing horizontally upon its hinges. This sash is pivotally secured within a window frame 11. This frame is formed with weight wells 12 and 13 extending parallel to each other and along opposite sides thereof. Counter-weights 14 and 15 are positioned within these wells and are suspended from the ends of cables 16 and Those cables are wound around the trunnions18 and 19 of a window screen roller 20.; As particularly disclosed in Fig. 3 of the drawings, this roller is formed in two parts,a main portion 21 of which is semi-circular in section and is supplemented by a small semi-circular section around which an arcuate clamping portion 22 is seated. This portion is held tothe main part of the roller by means of screws 23 and is adapted to bind the end of a reticulated fabric 24 to the roller. This fabric is preferably formed of wire and is semi-flexible so that it may be wound around the roller. The fabric screen 24 is of a slightly greater width than the window opening and therefore is positioned within vertical slots 25, which extend the length of the frame sides and hold the screen so that it will seal the opening. The lower edge of the screen is bound by a, metal strip 26, particularly disclosed in Fig. 7 of the drawings. This strip is folded twice and incloses the folded lower edge of the screen, thus securely holding the screen fabric and preventing it from loosening. Mounted on the back side of the binding strip 26 is a metal counterweight 27 which adds sutlicient weight to the screen to counterbalance the weights l4 and 15.. This Eli counterweight strip is secured to the metal binding strip 26 and a facing: strip 27 by means of wood screws 34. The facing strip 27' is made of wood and. finished to match the woodwork within the room. W hen the binding and facingstrips are assembled, as show in the drawings, the ends of the metal strip will extend outwardly and slide along the vertical slots 25 in the frame. The tacing lormed with a recess 28 within which the fingers may be positioned and the screen raised and lowered. This facing is adapted to be drawn down to bear upon the window sill 29. When in this position the window opening; will be closed by the screen.

It will. be understood t-hat thc casement windows may be designed to swing either inwardly, or outwardly. In Fig. 5 the window shown as swinging inwardly, while in Fig. 6 the window swings outwardly. In either case the operation of the screen will be the same. i u

In order that the screen may be easily renewed, or removed, i1. desired, a removable head board 30 is positioned at the top of the frame and secured in place by two angle members 31 and This board forms a slotted opening 33 through which the screen. may pass and, when removed, allows the screws 23 to be withdrawn from the roller.

"lhis will allow the removal ol the clamping portions 22 ot' the roller and permit the screen fabric to be drawn therefrom,

When this device is used, the binding edge of the screen. may be grasped and drawn down. This will unroll the screen from the roller against the action. of the counter-- weights 1% and 15, and will permit the screen to stand at rest when it has been sufficiently dawn. In case the use of the screen is not desired, it may be raised and will automatically be wound upon the roller 21 as the counterweights are lowered within their wells. It the screen is to be re moved the head board 30 is taken out of its position and the roller parted, as previously described. The screen may be re moved from, the binding strip by loosening mo em the screws 34 toeeparate the counterweight strip 27 and the facing strip 27, after which the metal binding strip 26 may be sprung from the vertical slots 25 and slipped endwise from the screen. A. reversal of this operation will rebind the screen and remount'it upon its roller.

ltfwill thus be seen that the screen here disclosed is simple in its construction, does not require special mounting members, and may be easily drawn into a closing position over a window opening, or may be raised out of the way, and furthermore may be easily renewed, when desired, without dismantling the entire window'strame.

While I have shown the preferred construction of my window screen as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of my invention.

1 claim:

Ina window screen, the combination with a window frame, of a screen roller positioned within said frame and at the upper end thereof, a. flexible screen fabric detacha'bly secured to said roller; said frame having a slotted opening through which the roller is mounted upon. its support; a removable closure member adapted. to partially obstruct said opening and to provide a passage-wity through which the screen 'may travel, guide grooves formed alongthe opposite sides of the frame opening within which the edges of the screen. move, a counterweight strip fastened along the lower edge of the screen, a facing strip upon the opposite side oi? the screen and to which the counterweight strip is secured, cables wound around the ends of the screen roller, and

conntcrweights secured to the ends of the cables to counterlnilance the counterweight strip and the screen.

In testimony whereof I have signed my name to this specification.
